About this data. Computed from NOAA's HURDAT2 Atlantic and Northeast Pacific hurricane databases (hurdat2-1851-2025-02272026.txt), covering 1855–2025. Tracks are recorded every six hours and are interpolated to one-hour steps before distances are measured, so closest-approach figures are not distorted by the sampling interval. Distances are measured to the parish's Census internal point, not to its nearest boundary, so a storm listed at 55 miles may still have crossed the coastline — see Methodology. Records before about 1900 are sparser and less precise than modern ones, and storms that stayed at sea were less likely to be recorded at all.

How often to expect a storm
